Removing the Spring cont'd
12. Use a 1/2" wrench on the flats of the threaded rod to hold
the threaded rod. Use a 1-1/4" wrench to turn the barrel
nut and compress the spring until it just begins to rotate.
13. Remove the lower control arm pivot bolts. Disengage the
lower control arm from the frame. See Figure 3.
14. Remove the compressed spring and the front coil spring
compressor as an assembly.
15. Measure the compressed length of the spring, and count
the number of coils between the support plates. See
Figure 4. Record this data, because it will be used to
determine the correct location of the support plates in the
new spring.
16. Hold the threaded rod with a 1/2" wrench to keep it from
turning. Using a 1-1/4" wrench, loosen the barrel nut to
release tension.
Installing the New Spring
1. Insert the threaded rod into the new coil spring. Refer to
the data recorded in Step 15, and install the support
plates in the same locations as in the old spring. As-
semble the lower ball, thrust bearing, and barrel nut.
2. Verify that the new spring has the correct number of coils
between the support plates as recorded in Step 15.
3. Compress the coil spring to the original measured height.
4. Refer to the vehicle service manual, and follow the
procedure to install the new spring.
Removing the Tool from the Spring
1. SLOWLY loosen the barrel nut until the spring is no longer
under tension.
2. Remove the barrel nut, thrust bearing, and lower ball from
the threaded rod.
3. Turn the threaded rod until the upper plate winds down
the coil spring far enough so the pin can be removed from
the upper ball seat.
4. Remove the upper support plate, the upper ball, and the
threaded rod.
Maintenance
1. Each time before the tool is used, clean and lubricate the
threads on the threaded rod.
